Fractal BlackTM is the coating of choice where low reflectance / high emissivity is required across the spectrum from the UV through LWlR — typically for stray-light suppression. In addition to its superior optical performance Fractal BlackTM delivers many other attributes important in space applications:
- Essentially zero outgassing
- Vacuum and thermal—vacuum cycling qualified
- Operating temperatures from (-)269°C to (+)350°C
- No particulation
- Only a few microns thick
- Compatible with virtually all substrate materials
Fractal BlackTM has been extensively tested and qualified for space applications and is applied in a variety of space programs including among others:
- ESA/ NASA James Webb Space Telescope (JWST) – NIRSpec
- ESA Bepi Colombo
- Meteosat Third Generation (MTG) satellites
- EnMAP-FSSA satellite
Fractal BlackTM was thoroughly tested and qualified for thermal cycling, thermal vacuum cycling, cryogenic temperature performance, outgassing, space atomic oxygen, reflectance after environmental exposure, adherence. Detailed BRDF data is available for VIS. SWIR, MWIR and LWIR.
